Let first term of an AP is a and Common difference d

9th terma + 8d = 0a = - 8d...........(1)

29th terma29 = a + 28d = - 8d + 28d = 20d

19th terma19 = a + 18d = - 8d + 18d = 10d

Therefore, a29 = 2 a19

Use log a + log b = log(ab)log a - log b = log(a/b)

4 log4 + 2 log 5 - log 15

log 4⁴ + log 5² - log 15

log (256 × 25)/15

log (256×5)/3

log(1,280/3)

the answer is option b

the answer is option B

thank u so much for fastly reply

P(x ) = ax² + bx + cput x = 1

P(1) = a + b + cbut a + b + c = 0so, P(1) = 0so, x = 1 is the root of P(x )

595 is the answer because u need to divided 70% and 255

3/5* 13/3= 39/15= 13*3/5*3= 13/5please like the solution 👍 ✔️

Area of shaded region=(1/2)*base*height=(1/2)*(10-6)*3=(1/2)*4*3=6cm^2

The design as a whole is to provide a randomly determined integer from one to six, each of those values being equally likely to militate against concerns that the faces of dice cause a small bias. For a single roll of a fair s-sided die, the probability of rolling each value is exactly 1/s-an of a discrete uniform distribution. For n multiple rolls, with a s-sided die the possibility space is equal to sn. So, for n rolls of an s-sided die the probability of any result is 1/sn. As the number of dice increases, the distribution of the sum of all numbers tends to normal distribution by the central limit theorem.

If you take the numbers 1,2....6 then add opp faces! You could have 1+2=3. 4+5=9. remember you could have other combination,,this is random, but for the example chosen.......It only leaves,the two numbers we have not used 6,3,,6+3=9

When the die is rolled then total outcomes = 6

Number appearing on upper face is less than 2 which is only 1. Thus possible outcomes = 1

Probability of getting number less than 2 on upper face= 1/6

(d) is correct option

any other method is there?

hit like if you find it useful

thanks

-44/72

-22/36

-11/18 , is simplest form.

1) - 44/72 = - 4/18 = - 2/9

2) - 8/10 = - 4/5

A die is thrown twice n(s)=36The probability of getting same number is (1,1)(2,2)(3,3)(4,4)(5,5)(6,6) i.e n(A)=6Ans. P(A)=n(A)/n(s)= 6/36=1/6.So, The Answer is 1/6

not clear picture

thank you

The answer to this question are: equal,different.

Number of event number= 3total event = 6probability=3/6=1/2

We know,Surface area of cube = 6*(side)^2

As one face of six faces of all six cubes are joined to face of seventh cube then only five faces of six cubes form the surface of toy

Therefore,Total surface area of toy= 6*[5*side^2]= 6*[5*root(7)^2]= 6*(5*7)= 210 cm^2

Total outcomes=6No. of vowels=a,e,a=3

Probability=3/6=1/2

no of even number possibilities=3hence probability =3/6=1/2

possibilities of sum 10 are (4,6),(6,4),(5,5) total outcomes are 36 so probability of getting sum 10 is = 3/36 = 1/12

at least 10 so possibilities are (4,6),(6,4),(5,5),(5,6),(6,5),(6,6)so probability=6/36=1/6

is it right...... and complete answer

i have just solved it.. you can check it yourself

9/10 is the correct answer for this question Thank you

9/10 is the correct answer...

9/10 is the correct answer

9/10 is equal to 0.9

where is the question

9/10 is the correct answer

herein you need to find the LCMhenceLCM of 8 and 108|102|4|52|2|52|1|55|1|1hence LCM is 5*8=40hence in 40minutes time

Thanks for reply my question...

Total outcomes = 6probability of getting a 3 = 1/6probability of getting an odd number = 3/6 =1/2probability of getting a no. greater than 1= 5/6
